Nasdaq's Q1 FY2026 GAAP diluted EPS jumped 33.3% to $0.91, while the press release led with the +21.5% non-GAAP figure of $0.96. Net revenue grew 13.8% to $1.41B and operating margin expanded 250 basis points to 46.7%. The 10-Q reveals what the 8-K narrative buried: Market Services gross revenue fell 8.1% year over year, operating-company IPOs collapsed 67% (offset by a SPAC surge), and Non-US revenue grew 57%. This analysis unpacks the leverage math, the IPO mix shift, the Nordic divestiture optic, and the geographic profile change that now changes Nasdaq's risk surface.
United Rentals reported Q1 2026 revenue of $3.985 billion (+7.2% year-over-year), adjusted EPS of $9.71, and raised full-year guidance — and the 10-Q filed April 22, 2026 lets a retail reader see the margin picture management's headline compression language hides. Net margin printed 13.32%, down 60 basis points year-over-year. Back out the $29 million after-tax benefit from the 2025 H&E merger break-up (which will not recur) and the new $45 million Q1 2026 restructuring charge (which did not exist last year), and underlying net margin is about +20 basis points year-over-year. The segment split shows the real operating story: General rentals gross margin +150 bps to 33.8% while Specialty gross margin -170 bps to 41.4% on a mix-driven drag that is not in the press release's one-sentence treatment.
CSX Corp.'s Q1 2026 10-Q, filed April 22, 2026, shows operating margin hitting 36.0% — a 558 basis-point year-over-year expansion and the best Q1 in the eight-quarter window MetricDuck tracks. The 10-Q rail-segment footnote discloses a $44 million gain on property disposition embedded inside the $153 million expense decline — a line the 8-K press release and the earnings-call narrative did not itemize. Backing it out, 'core' margin expansion is closer to 430bps and underlying operating-income growth is about +16%, not the headline +20%. Freight receivables also jumped 15.4% quarter-over-quarter against flat sequential revenue, creating a $130 million working-capital drag that softens the cash-earnings story.
TJX Companies posted Q4 earnings growth of 27.6% while Home Depot fell 14.6% in the same quarter — a 42-percentage-point divergence in one tariff-disrupted retail environment. A $419M credit card interchange settlement distorts every FY2026 margin metric, inflating SG&A leverage, boosting operating leverage from 1.65x organic to 2.1x reported, and adding $0.14 to EPS. Strip the settlement and the real story inverts: FY2027 guidance represents 5.2% organic growth rather than deceleration, and International is the strongest margin improver across all four segments.
Intercontinental Exchange delivered 20.7% EPS growth on 7% revenue growth in FY2025 — a 95% incremental margin that screams compounding monopoly. But the 10-K reveals operating cash flow grew just 1.1%, the '51% recurring revenue' claim masks a largest segment that's 62% transactional, and $160 billion in clearinghouse assets make every screener metric wrong. At 28× earnings, the filing quietly contradicts the growth narrative.
Dollar General reported a 107-basis-point gross margin recovery in its FY2025 10-K — but the filing's custom XBRL disclosure reveals that 75% came from inventory shrink reduction, a one-time operational fix with a calculable ceiling. Meanwhile, the WOTC tax credit expiration creates a $0.29-$0.46 EPS headwind that $69M in interest savings from $1.65B in debt paydowns can only partially offset. With ROIIC at -137% and the stock at 20.9x earnings, the filing shows a bridge year — not the steady-state compounder the multiple implies.
Wabtec reported $6.83 in GAAP EPS for FY2025 — but $461M of acquisition charges obscure a business generating 56% incremental gross margins and 17.5% adjusted operating margins. Meanwhile, $735M of off-balance-sheet working capital tools make the cash conversion cycle look 14 days better than it actually is. We apply a three-layer 'Acquisition Opacity Framework' to reveal the real economics behind the largest locomotive maker's most aggressive M&A year.
Netflix generated $9.46 billion in free cash flow in FY2025 — more than Amazon, on one-sixteenth the revenue. The 10-K reveals a structural inflection: content payments decelerated from +29% to +4%, driving a 47% incremental operating margin. But $45 billion in total obligations and guild agreements expiring mid-2026 complicate the cash machine narrative.
McDonald's cut share buybacks by 27% in FY2025 while spending a record $3.365 billion on expansion — a paradox until you see the 10-K's franchise economics. The filing reveals a 90.3% incremental franchise margin, meaning every new restaurant dollar is more profitable than the last. This analysis unpacks the capital allocation pivot, the emerging $647M technology platform, and the real estate fortress financing it all through Euro debt at half the U.S. rate.
Autodesk grew revenue by $1,075 million in FY2026 — and spent $4 million less on sales and marketing than the year before. The FY2026 10-K reveals that the channel transition from 42% to 63% direct sales is recapturing $284 million in distributor margin while .DWG file format lock-in keeps customers in place despite the most aggressive go-to-market restructuring in enterprise software history. But half of revenue now comes from construction software, making this 'design company' increasingly a cyclical bet that the 9x revenue multiple may not adequately price.
Robinhood's pre-tax income nearly doubled in FY 2025, growing 98% to $2.1 billion on a 68.3% incremental operating margin. But a $572 million tax swing compressed headline net income growth to 33%, masking the operating breakout. Our novel revenue fragility scoring reveals only 24% of HOOD's $4.5 billion revenue is structurally durable — with $2 billion in PFOF-dependent trading and event contract revenue facing specific 2026 regulatory catalysts.
AvalonBay Communities grew FFO per share 3.8% to $11.41 and launched a $488 million buyback program — its first ever — yet the stock fell 18%. The 10-K filing reveals AVB is running three simultaneous capital allocation experiments through a single balance sheet that swung from net cash to net debt in one year. With $3.3B under construction, $1.5B+ in near-term refinancings, and ~$0.24/share of hidden 2026 headwinds, the math either compounds or collapses.
Interactive Brokers grew revenue 20% to $6.2 billion with a 77% pretax margin — but this isn't really a trading platform. The 10-K reveals 57% of revenue is net interest income, and rate cuts paradoxically helped: NII grew 13% despite 27bps of margin compression because $29.6B in balance growth overwhelmed the rate impact. A structural 0.50% spread floor creates a ~$650M NII minimum. Meanwhile, 76% of net income flows to the Peterffy family through the LLC structure — public shareholders get 24% of a financial machine with zero debt and $203B in liquid assets.
Cigna Group added $27.8 billion in new revenue in FY 2025 — and generated just $220 million in additional operating income. The 10-K reveals Evernorth's PBS sub-segment margin collapsed 55 basis points to 2.65% as the rebate-free transition extracted ~$722 million in foregone profit, exceeding the company's own $500 million optimization savings target. Meanwhile, CI simultaneously ran a $749 million restructuring program and acquired $548 million in new specialty pharmacy goodwill, funded by a $4.5 billion debt issuance.
Expedia reported 41.8% operating income growth on 7.6% revenue growth — 5.5x operating leverage that made FY2025 look like a transformation story. But the 10-K reveals that revenue margins were flat at 12.3% in both years, meaning every basis point of margin expansion came from cost cuts. The consumer-facing B2C business grew just 2.4% while B2B drove 18.2% growth. And the record $3.11B FCF is partially inflated by a $10B deferred-bookings tailwind that reverses if bookings slow. What replaces the restructuring story?
Royal Caribbean improved its debt-to-equity ratio by 53% — from 4.54x to 2.13x — without paying down a single net dollar of its $21.3 billion debt. Instead, the cruise giant doubled shareholders' equity through retained earnings. Our deep dive into the FY2025 10-K reveals the 55% incremental operating margin engine, $7.2 billion in government-subsidized ship financing, and the $7.6 billion OCF threshold that determines whether this strategy compounds or collapses.
United Airlines generated $59.1 billion in record revenue in FY2025, yet its 7.6% return on invested capital barely clears its 6.2% cost of debt. The 10-K reveals three businesses traveling in three different directions under one ticker: a base airline losing pricing power (PRASM -2.9%), ancillary fees growing at 6.7%, and MileagePlus — now fully unencumbered — surging at 10.3%. At 5.75x EV/EBITDA, the market prices all three as one.
Bank of New York Mellon reported record revenue of $20.1 billion and 28.4% ROTCE in FY 2025 — numbers that suggest an efficiently run financial institution earning outsized returns. But the 10-K reveals a paradox: one segment generates 49% operating margins on infrastructure that moves $614 billion in securities, while another runs at 17% margins with declining revenue and $16.8 billion in goodwill from an 18-year-old acquisition. At 15.5x earnings, the market prices one company. The filing shows it's two.
PNC Financial Services reported record 21% EPS growth in FY2025 — and the stock trades at 10x forward earnings, pricing in zero growth. Four widely-cited red flags explain the market's skepticism: collapsing cash flow, inflated earnings, a stagnant core segment, and stretched valuation. The 10-K disproves all four. But two genuine risks survive the correction cascade: capital markets revenue cyclicality (47% of fee growth from a +24% surge) and a concentrated CRE office maturity wall (57.7% criticized, 38.7% maturing in 12 months).
Boston Scientific has written off $9.9 billion in cumulative goodwill impairments — 35% of every dollar ever booked. Yet in FY2025, the serial acquirer's ROIC crossed 9.1% for the first time in 20 quarters. Then BSX announced $14.5 billion for Penumbra, which will spike leverage from 1.95× to ~4.1× net debt/EBITDA — landing 0.65× below the covenant ceiling. The 10-K reveals a company at a binary inflection: the acquisition lifecycle model either compounds from here, or a history of goodwill destruction repeats at unprecedented scale.
IBM reported a 76% net income surge in FY2025 — its best earnings growth in over a decade. Two weeks later, the stock crashed 13%, erasing $31 billion, when Anthropic announced Claude Code could automate COBOL modernization. The 10-K reveals both reactions were wrong: two non-recurring events inflated earnings by $3.1 billion, true growth was 8-9%, and consulting — the supposed AI victim — is only 17.1% of IBM's profit. The real story is a quiet software takeover generating 61.7% of segment profit at 31.1% margins.
Spotify nearly doubled net income to €2.2 billion in FY2025 — the best year in the company's history — and Wall Street responded with 33 Buy ratings. But the 20-F reveals that €510 million of the profitability improvement came from a one-time deferred tax asset recognition that will never recur. With unrecognized DTAs exhausted from €818 million to €41 million, FY2026 net income may be flat or decline even as operating income grows 20%. The trailing P/E of 46.6x is tax-inflated; the tax-normalized P/E is 50-57x. Meanwhile, €1.5 billion in exchangeable notes mature in March 2026, the first-ever buyback program is accelerating, and a €358 million royalty lawsuit threatens the audiobook bundling strategy.
Shopify's gross margins have declined from 50% to 46% over six quarters. Most investors see this as a red flag. But Shopify's FY2025 10-K reveals a counter-intuitive dynamic: as lower-margin Merchant Solutions grows to dominate the revenue mix, operating margins are actually expanding — because it needs dramatically less incremental S&M and R&D. The question is whether fintech risk changes this equation.
AppLovin reported 70% revenue growth in FY 2025 — but the 10-K reveals nearly all of it came from AI pricing optimization (+72% revenue per install), not reaching more users (+3% install volume). With 99.3% incremental operating margins, Cash ROIC of 108.5%, and a $272 million Singapore tax benefit expiring June 2028, the filing paints a picture of extraordinary economics at an extraordinary price. Our 4-Component Growth Sustainability Model separates the $228 billion valuation into testable monitoring metrics.
Vertiv Holdings reported 168.8% net income growth in FY 2025, but our earnings quality decomposition reveals that $203.5 million — nearly one-quarter — came from a non-repeating tax rate correction. The remaining 76% is durable operating leverage on $10.2 billion in revenue, backed by a $15 billion backlog with SaaS-like deferred revenue visibility. But the filing also reveals asymmetric risks: no disclosed cancellation penalties on that backlog, a widening GAAP-to-adjusted earnings gap, and percentage-of-completion estimation risk that grows with project scale.
